Yep, I'm onto it. I'll put this one to bed and let you know how it goes once it's all done. Thanks for your help. Rob

Not an exact way, but by comparing the duration thats advertised,and looking at the duration at .050,you get a pretty good idea how fast its climbing by comparing two different grinds of a similar size. If you ran a comp 292,you would need a 3000+ stall and around 4.10 gears,but at .050 its at 244 duration,kinda see what I mean by comparing the difference between advertised and the .050 measurement?

Thanx rifraf. I kinda knew that the cam specs are the most important factor, but was thinking that the profiles, like aggressive lobe ramps can't really be measured by specifications and that maby that's what he was implying. I know that's what gives Comp Cams an advantage. This cam I've chosen has got all the specs I want and it's on the limit, or even just past it for a docile street machine. That's fine as it's my hobby car and it'd do less than 2000 miles a year! Sometimes people rate products as how they were years ago, but they forget that products need to improve with time for consumers to continue to purchase them. Bit like the Champion spark plug sarga which I'm closing right now lol!

Thats funny,I know what you mean. As for your your friend,I can relate,but when it comes to cams I have found that the specs to achieve what your after outweigh the sticker you get in the box,providing its a good quality cam. Many times I have had to have a cam ground to my specs because I couldn't find one that did what I wanted,one of the cool things about owning a sb chev is the massive variety of cams out there. Its a rare day that you cant find near exactly what your after for a sb chev,tell your freind to think outside the box"with his favorite name".

He does'nt like the brand. I think he's just being narrow minded as he loves his Crane cam grinds. Like me, he is a mechanic but he's also built up a lot of SBC performance engines for customers and he knows what he's doing when it comes to modifications. But I think it's a romance thing that makes him choose his cams, much like someone choosing a Ford or a Dodge over a Chevy. I guess time will tell if the cam works for me and I'm sure it will. Can someone tell me why this thread has been moved? Does'nt it deserve full attention? Man if I see another 'which is better, a 400 or 383' or similar thread I'll go ape. This thread is just as worthy as most other threads. I'm beginning to take this personally lol.

Does he not like the specs or the brand? Ive had real good luck with sped pro cams,its just like any of them though,if you don't break em in right or put to much spring pressure on em or don't lube em or make sure the lifters spin easy,they all will go flat. I think you will like that setup a lot. Gm makes a break in lube oil additive that I always use on flat tappet cam motors,good stuff.

Careful on that spring pressure

Also,Ive found that cam likes to be run strait up,no advance needed.

Thanks again. Well I'm locked into the deal. I've ordered from Northern auto parts the EPS manifold, the Speed Pro cam grind CS1013R and the a set of stiffer springs. Specs for the cam are the following - 2000-4500 RPM Range, 288/298 Adv Dur, @.050 214/224, Lobe Sep 112, Lift 443/465. I spoke to a buddy of mine at a party last night and told him that that particular cam's on order. He told me those Speed Pro cams are *****, and that Crane and Comp' are the only way to go. He's probably right, but I don't hear anyone mentioning about missing lobes on a Speed Pro cams like I hear with Comp cams. Their grind patterns should not be that inferior to others or are they? I mean all they have to do is copy what's out there that works, and ensure their quality control's in gear. Anyways, I'm stoked about the service from Northern auto parts. I've used them before and could'nt be happier. This order also includes a timing gear set so the overall package weight would be a little on the Porky Pig side, yet the cost for shipping to my Australian door is a measly $40! I reckon I've saved between $200 and $300 Australian dollars rather than buying locally.

Yep,that sum-k1103 is a fair jump smaller smaller on the intake side so you would have more low end than the Monte,but less up top,but you also must factor in that its maybe stuffed in a 350? The more cubes you have,the more tame the cam will apear. I think for a dayley driver,that cam with an eps,which I realy like,and a 500-650"depending on your priorities" carb would be the sweet deal.

ive got a smallish cam in my monte ( 222/222 AT .447 LIFT) it sounds great and gets my 3500lbs daily driver down the track in 14.20 on street tires

Thanks fellas, good useful info there. The motor's in a 1971 HG Holden (GM) pick up that weighs probably the same, if not less than a 68 Camaro. It's appearance is not unlike your El Camino's, but again, probably the same dimensions as a 68 Camaro. It's rear end gearing is on the low side for such a torquey v8 to the point where I never give it full gas on take off. I'd say the gearing's around 3.55 or so. Yeah, the EPS manifold also means no adapter for my square bore Holley, which is a good thing seeing hood clearance is tight. Thanks. I love my 307 (bored out close to 327 cubes) and just about anything American, Fords included!

My friend put that cam in a 70 gmc 307 truck,he loves it, I noticed a slight lag right off take off though,but it was very minor. How heavy you are and how low your gears are will dictate how long the lag is,his truck is heavy and had pretty high gears so that would be a worst case scenario,it realy did run nice though,a very small stall would have made it perfect.

rifraf, would the summit 1103 cam be too much for a 307 that's had the usual breathing mods done and with a stock converter? I'm toying with a similar cam from speed pro or whatever they call themselves. I'm also going to get the EPS manifold, does anyone know anything useful about it? I'm choosing it over the performer manifold as I'm using a square bore vacuum secondary Holley.

I don't know what cubes you have,or what heads,but the older sb heads without rotators take the sum-k1103 no prob,and then some,in a 350 the 1103 sounds just a hair over stock but you can still hear it has a cam at an idle,and it works real nice with the stock converter,its right at that edge,and it still keeps good vacuum. That other one may sound stock,in fact,there are a lot of stock cams bigger than that. Just a heads up from a guy whos used em quite a few times. Maybe that other one is what your after?
